Patent JP-S6129975-A (JP)
Title: Absolute value circuit
Inventor: IZAWA YUHEI
IPC: G06G7/25
Filed: 1984-07-20
Abstract: PURPOSE:To improve the linearity without adjustment and the accuracy of arithmetic, to form simply a comparator, arithmetic amplifier, etc., into a large scale integration and to miniaturize them by providing an input waveform operating part, output selecting part and an output selection control signal generating part. CONSTITUTION:An input waveform operating part for consisting of a reverse- phase amplifier 1a, an output selection part for consisting of analog switches 2a and 2b and a normal-phase amplifier 2c and an output selection control signal generating part 3 for consisting of a comparator 3a and a logical inverter 3b are provided. When an input signal lies in a positive section, the output of the comparator 3a becomes positive logic, which is outputted from the amplifier 2c as it is. Thus the output of the inverter 3b becomes negative logic, and the switch 2b is turned off; therefore the no effect of output of the amplifier 1a appear on the amplifier 2c. When the input signal lies in a negative section, no effect appears in the same way. As a result the linearity can be improved without adjustment, and the accuracy of the arithmetic can be enhanced. Furthermore, the comparator, arithmetic amplifier, etc., can be easily formed into a large scale integration, and miniaturized.

Title: Pressure controlling system for parallel load in concentrated hydraulic system
Inventor: HASEGAWA AKIRA
IPC: F15B11/00
Filed: 1979-11-19
Abstract: PURPOSE: To save useless power consumption and to obtain an efficient operation of a concentrated hydraulic system, by providing a pressure control valve capable of changing the setting pressure of a main circuit automatically with change of the load pressure.  
     CONSTITUTION: In case that either of load pressures is raised to a level higher than the maximum value rached previously in a concentrated hydraulic system for driving a multiplicity of loads by a parallel circuit, the load pressure is taken out at a  shuttle valve group 1. This increase in the load pressure causes rise of the output  voltage of a pressure converter 2, which is in turn transmitted to a servo-amplifier  4. The output signal of this servo-amplifier 4 is tranmitted to a pressure control  valve 5, which in turn functions to raise the discharge pressure of a hydraulic pump  7 in a main circuit M. Here, the pressure control valve 5 is controlled automatically  to make the output pressure of the first pressure converter 6 raised by the rising of discharge pressure of hydraulic pump 7 equal to the sum of the output pressure of  the second pressure converter 2 and a bias voltage afforded from a bias voltage generator 3.

Title: Temperature characteristic compensator for hydraulic shock absorber
Inventor: FUSEN TOMEO
IPC: F16F9/52
Filed: 1979-11-22
Abstract: PURPOSE:To eliminate the need of mechanically moved parts and assure reliable and stable motion without a failure caused by a damage by inserting a cylinder made of a substance of a proper thermal expansion coefficient in an oil hole. CONSTITUTION:As an oil temperature rises in association with a variation in atmospheric temperature or a motion of a shock absorber, the viscosity is reduced so that a damping force produced in the vicinity of an orifice 9 and a valve 10 is also reduced. However, as a cylinder 13 is made of a substance of a higher thermal expansion coefficient than that of a piston rod 3 and fastened by the rod, a center hole 14 is contracted in association with a rise in temperature. The damping force produced in the hole 14 is increased, while the viscosity of the oil is reduced. Therefore, the reduced damping force created in the vicinity of the orifice 9 and the valve 10 can be compensated.
